definition | A Giant Gravity Corer is used to recover cores up to 6.5 meters in length. Normally operated from a hydrographic winch, this gravity core can travel through the water column at speeds up to 125 meters a minute, which reduces station time required, especially in pelagic ocean depths. | ||||||
